Three spade connectors are used to connect the motherboard of laptops together. And also, notice the hook-like cable that is used to lock your laptop screen.

Step 8: Remove excess screws from your old LCD screen with a screwdriver. If you find any spade connectors, make sure to detach them carefully.

Step 9: Put the new LCD screen into your laptop case and insert its connectors first, then attach screws to it. And re-connect all those spade connectors to their original locations.
